From my experience with grain alcohol and liquor stores:

I have bought Grave's Grain Alcohol which is 195 Proof and is
USP grade.  That is PURE (as in uncontaminated) alcohol - BUT
it does have water in it!!! Why???? - because when alcohol is
made to 200 Proof, it quickly absorbs water from the air until
it settles down to 195 Proof.  You can't get 200 Proof alcohol.

Where did you find Absolut at 196 proof? Btw, Absolut is made
in one of the Scandinavian countries, not Russia.

So, which brand name of alcohol do you use for rosin removal?

As an aside - does anyone have a homemade recipe for 
audio tape players head cleaner - denatured alcohol?
What do you use?
